If the device detects an invalid parameter, it will abort the command by setting BSY=0, ERR=1, ABT=1,
and interrupting the host.
If an error occurs, the device will set BSY=0, ERR=1, and DRQ=1. The device will then store the error
status in the Error Register and interrupt the host. The registers will contain the location of the sector in
error. The errored location will be reported with CHS mode or LBA mode; the mode is decided by mode
select bit (bit 6) of Device/Head register on issuing the command.
If an Uncorrectable Data Error (UNC=1) occurs, the defective data will be transferred from the media to
the sector buffer and will be available to be transferred to the host at the option of the host. In case of a
Read Multiple command the host should complete transfer of the block which includes error from the
sector buffer and terminate whatever type of error occurred.
All data transfers to the host through the Data Register are 16 bits, except for the ECC bytes, which are
8 bits.
